LGP2

LGP2 (Laboratory of Genetics and Physiology 2) is a protein that in humans is encoded by the DHX58 gene. It is a part of the RIG-I-like receptor (RLR) signaling pathway, which is a crucial component of the innate immune response to viral infections.

Function

LGP2 is a member of the DExD/H box family of RNA helicases. It acts as a negative regulator of the RLR pathway by preventing the interaction of MAVS (Mitochondrial Antiviral-Signaling protein) with RIG-I and MDA5, two other key proteins in the pathway. This regulation is essential for preventing excessive immune responses that could lead to harmful inflammation.

Clinical significance

Alterations in the function of LGP2 have been associated with a variety of diseases. For example, mutations in the DHX58 gene have been linked to increased susceptibility to viral infections. Additionally, dysregulation of the RLR pathway, in which LGP2 plays a key role, has been implicated in autoimmune diseases such as Systemic lupus erythematosus and Rheumatoid arthritis.
